Abstract: We discuss the general relativity effects acting on the radiation signal from the inner accretion flow. We consider the radiation flux and polarization properties originating from a blob of gas near a rotating black hole. The predicted observed polarization at infinity is changed from its local value due to strong gravity and fast orbital motion. Different processes can produce the observed pattern: in the context of Sgr A* flares, the synchrotron mechanism and the inverse Compton up-scattering appear to be the most likely mechanisms.
